- Procedure: Prepectoral implant-based immediate breast reconstruction
- Registration Number
- NCT06112977
- Lead Sponsor
- University of Oxford
- Brief Summary
The goal of this feasibility randomised controlled clinical trial (RCT) is to compare mesh-assisted to no-mesh pre-pectoral implant based immediate breast reconstruction in women undergoing mastectomy for treatment of breast cancer or for risk reduction of an inherited breast cancer risk.
The main questions it aims to answer are:
* To determine the feasibility of a definitive RCT comparing the clinical and cost- effectiveness of no- mesh versus mesh- assisted pre-pectoral breast reconstruction.
* To determine if it is possible to collect data to inform a future economic analysis on the use of mesh in breast reconstruction.
Participants will be randomly allocated to have their breast reconstruction either with the use of mesh or without the use of mesh prior to the start of the operation. Participants will be blinded to their allocation until day 90 post operatively. Participants will be asked to have medical photography and to complete a short quality of life questionnaire before and after surgery at 90 days prior to finding out their allocation.
- Detailed Description
Trial Design:
Restore-B is a prospective, multicentre parallel 2-armed single-blinded randomised controlled feasibility trial comparing no-mesh to mesh- assisted immediate implant-based prepectoral breast reconstruction surgery.
Patients will be randomised 1:1 to either the intervention surgery (no- mesh) arm or the control arm surgery (mesh-assisted).
Planned Trial Period:
The overall period of the trial is:
12 months recruitment, 3 months follow-up and 6 months data analysis and final reporting of results.
Trial Participants:
Women over 18 years old eligible for elective immediate prepectoral implant-based breast reconstruction with mesh for cancer treatment or risk reduction surgery
Intervention:
Immediate prepectoral implant-based (implant or expander) breast reconstruction without surgical mesh (ADM or synthetic).
Comparator:
Immediate prepectoral implant- based (implant or expander) breast reconstruction with surgical mesh (ADM or synthetic) (standard of care).

- Primary Outcome Measures
Name Time Method Feasibility of a definitive RCT comparing the clinical and cost- effectiveness of no- mesh versus mesh- assisted pre-pectoral breast reconstruction. 16 months * Number of patients eligible
* Number of patients consented and randomised within 12 months recruitment
* Number of patients lost to follow up/withdrawal
* Completeness of data per participant (%)
- Secondary Outcome Measures
Name Time Method Clinical outcomes in each arm 90 days - Number of clinical complications in each arm up to 90 days: seroma, infection, re-operation, haematoma, mesh removal, implant removal, revision surgery
Patient reported outcome: Breast-Q Breast Reconstruction Quality of Life (QoL) Measure 90 days post operatively Breast Q measures health related QoL and patient satisfaction in the context of breast surgery. The breast reconstruction module will be used in this study and measured pre- and post-operatively in each arm.
All BREAST-Q scales are transformed into scores that range from 0-100, independent of the type and number of modules. The scores are computed by adding the response items together and then converting the raw sum scale score to a score from 0-100. For all BREAST-Q scales, a higher score means greater satisfaction or better QOL (depending on the scale).Patient reported outcome: EuroQoL-EQ5D Quality of Life (QoL) Measure 90days post operatively Quality of life (QoL) questionnaires pre-and post-operatively at 90 days measured by EuroQol-EQ5D-5L.
This QoL questionnaire comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems (1-5). The patient is asked to indicate her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. A higher score indicates more severe or frequent problems.
